SPECIFICATION forming part of Letters Patent No. 700,909, dated May 27,1902. Application filed July 18,1901. Serial No. 68,711.4 (No model.)

T all whom, it may concern.-

Be it known that I, WILLIAM G. FRAZER, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented an Improvement in Fountain-Pens, of which the followingdescription, in connectionwith the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

1o This invention has for its object to provide a novel fountain-pen.

My invention relates particularly to fountain-pens of the classillustrated by United States patent of July 17, 1894, No. 523,234,

wherein the pen proper or nib, as it is sometimes called, is normallycontained within the ink-reservoir, from which it is expelled or causedto protrude for use by rotation of some part of the holder. In pens ofthe conzo struction shown in said patent of July 17,

1894, it is possible for the operator thoughtlessly to turn the crownplug or member of the holder while the cap is still in position coveringthe pen, with the result that the pen will be projected out from thereservoir against the cap, closing the end thereof, to the injury of thepen. Furthermore, there is no give whatever between the rotatablecrown-piece that ekpels the pen and the spiral 3o barrel and itsdelicate connections which actually expel the pen, with the result thatthe operator unless exercising great care is apt to turn the crown-piecevigorously and beyond the point at which the pen is fully expelled,causing breakage of some of the operating parts, for obviously after thepen has been fully expelled any attempt further to rotate thecrown-piece must cause breakage of some part of the connections.

The aim of mypresent invention is to eliminate these objectionablefeatures and to provide generally an improved pen of this type.

In the drawings accompanying this description, Figure l, in longitudinalsection, shows a pen illustrating` one embodiment of my invention,thepen proper being withdrawn within the reservoir and the end of thelatter closed by a cap; and Fig. 2, a similar view showing the capplaced upon the rotatable operating member and the pen expelled from thereservoir in position for writing.

In the embodiment of my invention selected for illustration herein andshown in the drawings, ct is the barrel or reservoir, of usual size,shape, material, and construction, the 55 same being provided at itslower end with a pen section or plug l), screwed into the end of thebarrel a. The barrel at its opposite upper end is also threaded toreceive the crown-plug c. The pen section or plug l) is 6o exterior] ythreaded to receive the cap (l, that may be screwed thereon to close thelower pen end of the barrel. The crown-plug c is perforated axially toreceive the shank e of the spirally-grooved head c, arranged Within thebarrel a. The said crown-plug c is counterbored at its outer end toreceive the crownoperating member j, which is fastened in suitablemanner, as by the pin f', to the end of the shank c', suitablepackingfz, as of cork, 7o surrounding the said shank beneath theoperating member f to prevent leakage outwardly around said shank. Thisoperating member f is "also in turn counterbored or recessed at f3,preferably conically, to receive the preferably conical nipple d uponthe end of the cap d, as shown in Fig. 2. The spiral groove or grooveseX of the head e receive the operating-pin c2 on the rod e8, lyingwithin and longitudinally of the barrel d and 8o carrying at itsopposite end the usual gold pen or nib el. The ends of this operatingpinc2 project beyond the spirally-grooved head e and enter and travel inthe diametral longitudinal grooves a', formed in the interior 85 wall ofthe barrel,said pin,with its rod c3,hav ing a movement longitudinal ofthe barrel, but being restrained from rotation therein by the ends ofthe pin e2 in said grooves a'.

lVhen the penis not in use, the parts are in 9o the position shown inFig. l, with the cap applied to the pen-section l) and closing that endof the barrel or holder, the opposite end being permanently closed bythe crown-plug c and parts carried by it. To place the pen in conditionfor use,the operator unscrews or removes-the cap d from the pen-sectiono and places the same upon the opposite end of the pen, inserting thenipple d into the recess f3 of the operating member f. The frictionalenxoo gagement of this nipple with the wall of the recess is such thatby rotating the cap in `its new position, Fig. 2, the operating memberfwill also be rotated, causing corresponding rotation of thespirally-grooved head e Within the ink-reservoir. Inasmuch as the pin e2cannot rotate,-the action of the walls of the spiral groove or groovesupon it is such as to cause the said pin to travel longitudinally of thebarrel in its grooves a', and this causes corresponding movement of therod e3 to expel the pen from the now open end of the barrel and placeitin the position shown in Fig. 2 ready for use. Inasmuch as theengagement of the cap-nipple with the Wall of the recess f3 isfrictional merely, should the operator attempt to turn-the cap and therecessed operating member to which it is applied farther than isnecessary fully toexpel the pen such attempt Will merely cause thenipple to slip within the recess of the operating member Without turningthe latter. Consequently no injury can resultvto any ofthe workingparts. The frictional engagement will always give before any of theWorking parts. Furthermore, as the rotatable operating member in or atthe crown of the pen is concealed or inclosed from exterior manipulationand operable i'rom the exterior only upon insertion of an operatingdevice, such as the cap-nipple, it is apparent that the pen cannot beexpelled while the cap is on and closing the end of the barrel.Consequently it is impossible to project the pen into contact with thecap to the injury ot' the pen. Thus it is impossible to injure theworking parts of the pen by turning its operating member too far, and itis also impossible to damage the pen proper or nib by attempting toexpel it without first removing the cap.

My invention is not limited to the particular construction here shownand described, for it is evident the same may be Varied withoutdeparting from the spirit and scope of the invention as here disclosed.

Having described my invention, what I claim, and desire tov secure byLetters Patent, 1s-

l. In a fountain-pen, the combination with the barrel or casing, of arotary pen-operating member mounted Within the upper open end of thebarrel and having its outer end within the plane of, but exposedthrough, the said open end, the said outer end of the rotating memberbeing shaped to receive a separate and'independent rotating device.

2. In a fountain-pen, the combination with the barrel or casing, of arotary pen-operating member mounted Within the upper open end of thebarrel or casing and having its outer end Within the plane of, butexposed through, the said open end, a removable cap rfor the lower endof the casing or barrel and the barrel or casing, of a rotarypen-operating member mounted within the upper end of the barrel orcasing and having a socket in its outer end accessible through the upperopen end of the said casing or barrel, and a removable cap for the lowerend of the casing or barrel having a nipple of a size to snuglyt saidsocket and form a frictional connection therewith; substantially asdescribed.

4. A fountain-pen comprising the barrel or casing, a pen-carrying rod ormember therein, a tubular crown-plug forming the upper end of the barrelor casing, a spirally-grooved head operatively connected with thepen-carrier rod and provided with a shank having a rotary operatingmember lying wholly within the outer end of said tubular plug andprovided in its outer end with a conical socket, and a cap removablyitting the lower end of the barrel or casing and provided with a couicalnipple to frictionally engage the said' socket and rotate thespirally-grooved head; substantially as described.

5. In a fountain-pen, the combination with the barrel or casing providedat its lower end with a removable cap, of a rotary operating memberwholly within the upper end of the barrel, but exposed through the upperend thereof, and means for frictionally connecting the said removablecap with the said rotary operating member and comprising a nipple andsocket shaped for frictional engagement, whereby when the said operatingmember has been sufiiciently rotated the connection between it and thecap will slip; substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

NVILLIAM Gr. FRAZER.
